Groundwater Sensor

The Groundwater Sensor detects free hydrocarbons in the C5 to C16 range on the water table in up to 20 feet deep monitoring wells.

Stay in compliance by detecting free hydrocarbon products on the water table in up to 20” deep monitoring wells. A Water Out alarm lets you know that the water level has fallen below the sensor and fuel can no longer be detected. The sensor’s watertight, lockable cap also prevents accidental fuel spills on the ground surface from entering and contaminating the monitoring

Key Features of the Groundwater Sensor

  • Fulfills local, state and federal electronic groundwater monitoring requirement

  • Ideal monitoring method for areas with high water table

  • Not sensitive to background vapors

  • Long-life, reusable sensing element

Key Benefits

  • Detects all liquid hydrocarbons in C5 to C16 range

  • Detects as little as 1/10" free product on water table

  • Water Out alarm informs you when water table is low and you are no longer in compliance

  • Responds to gasoline in 15 minutes or less; longer in other hydrocarbons in the C5 to C16 range

  • Simply remove sensor from well and expose to air after sensor alarms
